Molecular mechanisms of manganese mutagenesis.

The mechanism by which DNA polymerase discriminates between complementary and noncomplementary nucleotides for insertion into a primer terminus has been investigated. Apparent kinetic constants for the insertion of dGTP and dATP into the hook polymer d(C)194-d(G)12 with Escherichia coli DNA polymerase I (large fragment) were determined. The results suggest that the high specificity of base sele...

Molecular and Cellular Mechanisms of Mutagenesis

The important second part of the book, which is more cellular, concerns the cytoplasmic cytoskeleton and its potential relationship to the membrane. These subjects include the molecular architecture of the microvillus cytoskeleton, that of the placental microvilli, that of the brush border and its relationship to contractility, the involvement of membrane glycoproteins to attachment of microfil...

Molecular Cloning and Mutagenesis of Rat Glucocerebrosidase Gene

Purpose: The aim of this study was cloning the Gba enzyme in pUCBM21 plasmid, and making frame mutation on it and sequencing it. Materials and methods: mRNA was extracted from mouse spleen and glucocerebrosidase cDNA was synthesized and amplified by PCR with specific primers. cDNA was cloned in pUCBM21 and analyzed by restriction enzymes. A fragment of its sequence was deleted using MscI restr...

From Context-Dependence of Mutations to Molecular Mechanisms of Mutagenesis

Mutation frequencies vary significantly along nucleotide sequences such that mutations often concentrate at certain positions called hotspots. Mutation hotspots in DNA reflect intrinsic properties of the mutation process, such as sequence specificity, that manifests itself at the level of interaction between mutagens, DNA, and the action of the repair and replication machineries. The nucleotide...

Molecular Mechanisms of Recurrent Pregnancy Loss

Introduction: Pregnancy and health is the process in which the egg is fertilized and being able to survive. When pregnancy occurs under some conditions and the fetus is being at risk, it will lead to abortion that occurs involuntarily and spontaneously. Abortions that occur more than two or three times are called recurrent pregnancy loss (RPL). Various etiological factors involved in RPL, inclu...
